An enhancing inner structure of an inflating ball with an outer layer has a round inflated inner bladder by inflating an inflatable inner bladder which is processed in advance by a separating agent. Then the inflated inner bladder is wound by fabrics to form with an enhancing layer. Then, the enhancing layer is enclosed by a plurality of piece-like structures to be as an outer layer. The fabrics are mixed with foamed soft sponge rubber. Then the outer layer is seamed. Then the whole ball structure is heated. Since the foaming material on the outer surface of the enhancing layer is non-viscous in normal temperatures, and the inner bladder is processed in advance with a separating agent; thereby, when the air in the bladder is released; the inner layer and the enhancing layer will separate naturally.
